向多个FCM令牌发送通知

Question

我有一个课程（PushNotificationSender）。此类包含一个称为sendPushNotification的函数，该函数接收FCM Token，Notification title和Notification body。鉴于我知道他们的FCM Token，因此我已使用它成功地向一个用户发送了通知。

我的目标：使用此功能将相同的通知发送给多个用户。

我已经尝试为每个用户的FCM Token调用它，并且我还尝试更改该函数的参数以获取一个令牌数组，而不只是一个令牌数组，但是什么都没有起作用。关于如何完成升级的任何想法？

PushNotificationSender：

class PushNotificationSender {

    init() {}

    // MARK: Public Functions

    public func sendPushNotification(to token: String, title: String, body: String, completion: @escaping () -> Void) {
        let urlString = "https://fcm.googleapis.com/fcm/send"
        let url = NSURL(string: urlString)!
        let paramString: [String : Any] = ["to" : token,
                                           "notification" : ["title" : title, "body" : body],
                                           "data" : ["user" : "test_id"]
        ]

        let request = NSMutableURLRequest(url: url as URL)
        request.httpMethod = "POST"
        request.httpBody = try? JSONSerialization.data(withJSONObject:paramString, options: [.prettyPrinted])
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        request.setValue(//key, forHTTPHeaderField: "Authorization")
        let task =  URLSession.shared.dataTask(with: request as URLRequest)  { (data, response, error) in
            do {
                if let jsonData = data {
                    if let jsonDataDict  = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: AnyObject] {
                        NSLog("Received data:\n\(jsonDataDict))")
                    }
                }
            } catch let err as NSError {
                print(err.debugDescription)
            }
        }
        task.resume()
        completion()
    }

}

要发送多个令牌，您应该将它们放入registration_ids。完整文档here

并且，请不要在代码中共享私钥。不安全。

完整代码：

class PushNotificationSender {

init() {}

// MARK: Public Functions

public func sendPushNotification(to token: String, title: String, body: String, completion: @escaping () -> Void) {
    let urlString = "https://fcm.googleapis.com/fcm/send"
    let url = NSURL(string: urlString)!
    let paramString: [String : Any] = ["registration_ids" : ["<token1>", "<token2>", "<token3>"],
                                       "notification" : ["title" : title, "body" : body],
                                       "data" : ["user" : "test_id"]
    ]

    let request = NSMutableURLRequest(url: url as URL)
    request.httpMethod = "POST"
    request.httpBody = try? JSONSerialization.data(withJSONObject:paramString, options: [.prettyPrinted])
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue("key=AAAAUgiuQUM:APA91bFZvhw4nZzZUb32_E_hr3SI1seLNLxHiYGa8yZjwOLUrhSdViK-Sb4bwwveR9bXq-1TR2_xFCNXUoFJajPp6YcKLDGpADoq7BlBmvIU-mGxlH_SjyX3mpZ0jajFzEf0EoiZgd3w", forHTTPHeaderField: "Authorization")
    let task =  URLSession.shared.dataTask(with: request as URLRequest)  { (data, response, error) in
        do {
            if let jsonData = data {
                if let jsonDataDict  = try JSONSerialization.jsonObject(with: jsonData, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: AnyObject] {
                    NSLog("Received data:\n\(jsonDataDict))")
                }
            }
        } catch let err as NSError {
            print(err.debugDescription)
        }
    }
    task.resume()
    completion()
}

}
